Credit Line Repayment Tool

WHAT IT DOES

Credit Line Repayment Tool enables users to repay outstanding debt on their credit lines. The tool reads your connected wallet address, credit line contract address, outstanding debt amount, interest accrued, repayment amount, token address, token decimals, repayment schedule, late fees, current block timestamp, and payment history. It displays the outstanding debt, accrued interest, any late fees, the total amount due, and your current balance. You can choose to repay a specific amount or the full outstanding balance. Once confirmed, the tool executes the repayment transaction, reducing your debt and settling accrued interest and fees.

HOW TO USE

Connect your wallet and select your network. Enter the credit line contract address and the token address you used for borrowing. Choose whether to repay a specific amount or the full outstanding balance. If repaying a specific amount, enter the amount in the input field. Click "Fetch credit line status" to load your credit line details including outstanding debt, interest accrued, late fees, total due, your token balance, and the next due date. Review all details carefully—the tool will show you whether you have sufficient balance to cover the repayment. If everything is correct, click "Repay" to execute the transaction. The tool will handle token approval if needed and confirm the repayment.

THE REAL MECHANISM — DEBT REPAYMENT WITH INTEREST AND FEE SETTLEMENT

Unlike simple transfers that only send funds, this tool implements a structured debt repayment system with proper accounting. The getRepaymentInfo function returns the outstanding debt principal, accrued interest, late fees, and the next due date. The total due is calculated as debt + interest + fees. The repay function verifies that the repayment amount is sufficient to cover the specified portion of the debt, processes the token transfer from the borrower, and allocates the payment in the correct order: (1) late fees first, (2) accrued interest second, (3) principal last. The tool reads the token balance and validates that the user has sufficient funds to cover the repayment amount. The repayFull option allows users to clear their entire balance in one transaction. All arithmetic uses ethers.js BigNumber with the token's decimal precision, and gas costs are reported using receipt.effectiveGasPrice. The tool includes approval handling for the credit line contract.

WHAT IT CANNOT SEE

Cannot verify off-chain repayment capacity—the tool has no visibility into the borrower's financial situation beyond the on-chain balance. It cannot predict future interest accrual—interest continues to accrue until the debt is fully repaid. It cannot ensure payment allocation accuracy—the tool relies on the contract's payment allocation logic. It cannot detect if the credit line contract contains vulnerabilities or malicious code—the tool does not audit the contract logic. It cannot recover funds if the repayment is executed on an inactive or compromised credit line.

PLEASE NOTE — EVM CHAINS ONLY

This tool exclusively supports EVM-compatible chains where ethers.js can connect via standard JSON-RPC. It does not support non-EVM chains such as Solana, Tron, Starknet, SUI, TON, Aptos, Bitcoin, Cosmos, or XRP. The credit line contract must implement the specific interface expected by this tool (repay, getRepaymentInfo, getToken). Always review the repayment terms and ensure you have sufficient balance before repaying. This tool is a debt management interface, not a financial advisor or lending consultant.
